Foreword The development work on this specification was done by the SFF Committee, an industry group. The membership of the committee since its formation in August 1990 has included a mix of companies which are leaders across the industry. When 2 1/2" diameter disk drives were introduced, there was no commonality on external dimensions e.g. physical size, mounting locations, connector type, connector location, between vendors. The first use of these disk drives was in specific applications such as laptop portable computers and system integrators worked individually with vendors to develop the packaging. The result was wide diversity, and incompatibility. The problems faced by integrators, device suppliers, and component suppliers led to the formation of the SFF Committee as an industry ad hoc group to address the marketing and engineering considerations of the emerging new technology. During the development of the form factor definitions, other activities were suggested because participants in the SFF Committee faced more problems than the physical form factors of disk drives. In November 1992, the charter was expanded to address any issues of general interest and concern to the storage industry. The SFF Committee became a forum for resolving industry issues that are either not addressed by the standards process or need an immediate solution. Those companies which have agreed to support a specification are identified in the first pages of each SFF Specification. Industry consensus is not an essential requirement to publish an SFF Specification because it is recognized that in an emerging product area, there is room for more than one approach. By making the documentation on competing proposals available, an integrator can examine the alternatives available and select the product that is felt to be most suitable. SFF Committee meetings are held during T10 weeks (see www.t10.org), and Specific Subject Working Groups are held at the convenience of the participants. Material presented at SFF Committee meetings becomes public domain, and there are no restrictions on the open mailing of material presented at committee meetings. Most of the specifications developed by the SFF Committee have either been incorporated into standards or adopted as standards by EIA (Electronic Industries Association), ANSI (American National Standards Institute) and IEC (International Electrotechnical Commission).

3. General Description

The 0.8 mm connection system of the Mini Multilane Connector is based on industry-proven card edge style contacts, which mate with a single wipe, and are very difficult to damage. The mating interfaces of paddle card to receptacle body and receptacle body to circuit board are common between SFF-8087 Mini Multilane 4X Unshielded Connector and SFF-8088 Mini Multilane 4X Shielded Connector. The shell is mounted separately to the body so that the stress imposed by insertion and removal of the cable plug does not affect the signal/body solder joints. This connector system was designed to satisfy the needs for gigabit serial data transmission applications where signals have rise times typically in the range of 100 ps over a nominal 100 ohm differential balanced copper link. Design goals were Minimization of crosstalk and Minimum transmission line impedance discontinuity across the connector interface at speeds of up to 10 Gb/s on both rows of contacts. The transmission line impedance of the connector itself (not including the termination interface to the wire or board) matches the electrical bulk cable within the tolerances allowed for the bulk cable. This connection scheme may be used in multiple places within a cabling environment. Though it has been designed for a 100 ohm environment this connector will function acceptably at other impedance levels (to be optimized on a case by case basis). This specification includes the Minimum lengths, widths and positional tolerances of the contacts. The connector is of a straightforward construction that does not rely on advanced materials or processes, and is physically robust. 4. Definitions and Conventions

4.1 Definitions

For the purpose of this specification, the following definitions apply: Advanced grounding contacts: Connector contacts that make first and break last and are capable of carrying power ground return currents and performing electrostatic discharge. Other terms sometimes used to describe these features are: grounding pins, ESD contacts, grounding contacts, static drain, and pre-grounding contacts. Alignment guides: Connector features that preposition insulators prior to electrical contact. Other terms sometimes used to describe these features are: guide pins, guide posts, blind mating features, mating features, alignment features, and mating guides. Board Termination Technologies: Surface mount single row, surface mount dual row, through hole, hybrid, and straddle mount. Cable Termination: The attachment of wires to the termination side of a connector. Schemes commonly used in the industry are IDC (Insulation Displacement Contact), IDT (Insulation Displacement Termination), wire slots, solder, weld, crimp, braise, etc. Contact mating sequence: Order of electrical contact during mating/unmating process. Other terms sometimes used to describe this feature are: contact sequencing, contact positioning, make first/break last, EMLB (early make late break) staggered contacts, and long pin / short pin.



Fixed: Used to describe the gender of the mating side of the connector that accepts its mate upon mating. This gender is frequently, but not always, associated with the common terminology "receptacle". Other terms commonly used are "female" and "socket connector". The term "fixed" is adopted from EIA standard terminology as the gender that most commonly exists on the fixed end of a connection, for example, on the board or bulkhead side. In this document "fixed" is specifically used to describe the mating side gender illustrated in Figure 4-1. Free: Used to describe the gender of the mating side of the connector that penetrates its mate upon mating. This gender is frequently, but not always, associated with the common terminology "plug". Other terms commonly used are "male" and "pin connector". The term "free" is adopted from EIA standard terminology as the gender that most commonly exists on the free end of a connection, for example, on the cable side. In this document "free" is specifically used to describe the mating side gender illustrated in Figure 4-1. Frontshell: That metallic part of a connector body that directly contacts the backshell or other shielding material that provides mechanical and shielding continuity between the connector and the cable. Other terms sometimes used to describe this part of a cable assembly are: housing, nosepiece, cowling, and metal shroud. Free Board: A connector that uses a free gender mating side and a termination side suitable for any of the printed circuit board termination technologies. Fixed Board: A connector that uses a fixed gender mating side and a termination side suitable for any of the printed circuit board termination technologies. Height: Distance from board surface to farthest overall connector feature. MSA: Multiple Source Agreement Mating side: The side of the connector that joins and separates from the mating side of a connector of opposite gender. Other terms commonly used in the industry are mating interface, separable interface and mating face. Offset: An alignment shift from the centerline of the connector. Optional: This term describes features that are not required by the SFF Specification. However, if any feature defined by the SFF Specification is implemented, it shall be done in the same way as defined by the Specification. Describing a feature as optional in the text is done to assist the reader. If there is a conflict between text and tables on a feature described as optional, the table shall be accepted as being correct. Reserved: Where this term is used for defining the signal on a connector pin its actual function is set aside for future standardization. It is not available for vendor specific use. Where this term is used for bits, bytes, fields and code values; the bits, bytes, fields and code values are set aside for future standardization. The default value shall be zero. The originator is required to define a Reserved field or bit as zero, but the receiver should not check Reserved fields or bits for zero. Right Angle: A connector design for use with printed circuit board assembly technology where the mating direction is parallel to the plane of the printed circuit board. SFP: Small Formfactor Pluggable



Single row: A connector design for use with surface mount printed circuit board assembly technology where the termination side points are arranged in one line. Single sided termination: A cable termination assembly style and a connector design style where only one side of the connector is accessible when attaching wires. This style frequently has IDC termination points that point in the same direction. SMT: Surface Mount Technology Straddle mount: A connector design style and a printed circuit board design style that uses surface mount termination points on both sides of the board. The connector is frequently centered between the top and bottom surfaces of the board. Straight: A connector design for use with printed circuit board assembly technology where the mating direction is perpendicular to the plane of the printed circuit. board Surface mount: A connector design and a printed circuit board design style where the connector termination points do not penetrate the printed circuit board and are subsequently soldered to the printed circuit board. Termination side: The side of the connector opposite the mating side that is used for permanently attaching conductors to the connector. Due to pin numbering differences between mating side genders the termination side shall always be specified in conjunction with a mating side of a specific gender. Other terms commonly used in the industry are: back end, non-mating side, footprint, pc board side, and post side. Through hole: A connector design and a printed circuit board design style where the connector termination points penetrates the printed circuit board and are subsequently soldered to the printed circuit board.

5.5 Connector Configurations

The Mini Multilane Series relies on a receiving body and paddle card, which are the primary elements to construct connectors. The primary elements provide a flexible means to implement solutions for diverse applications e.g., direct board-to-board implementations can incorporate the plug into the side of one board and mate directly to a receiving body on the other. Figure 5-1 is an example, which illustrates two styles of receiving bodies and how they become receptacles to receive the plug when encapsulated by the shell that is designed for an unshielded connector application.

FIGURE 5-1 GENERAL VIEW OF FIXED (RECEPTACLE) CONFIGURATIONS

SFF-8087 defines the free (plug) cable connector that incorporates the paddle card and the shell, which is used to encapsulate the receiving body to form a complete receptacle for use in unshielded applications. SFF-8088 defines the free (plug) cable connector that incorporates the paddle card and the shell, which is used to encapsulate the receiving body to form a complete receptacle for use in shielded applications.



The shell provides guidance and retention for the free (plug) cable connector, and absorbs the stress imposed by insertion and removal of the free (plug) cable connector. This protects the signal quality of the solder joints to the body. 6. Connector Dimensions

The dimensioning conventions are described in ANSI-Y14.5M, Dimensioning and tolerancing. All dimensions are in millimeters. Dimension related requirements for the connector system addressed in this document are specified in the tables and figures in this clause.
